Error merging dex

[AyokunlePaul]

Here's my build.gradle file(project)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
ext.kotlin_version = '1.1.51'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

}

allprojects {
repositories {
google()
jcenter()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

Here's my build.gradle(app)

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
compileSdkVersion 26
defaultConfig {
applicationId "i.am.eipeks.cloudinary"
minSdkVersion 17
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation group: 'com.cloudinary', name: 'cloudinary-android', version: '1.20.0'
implementation 'com.pusher:pusher-java-client:1.5.0'
implementation 'com.loopj.android:android-async-http:1.4.9'
implementation 'com.google.code.gson:gson:2.8.0'
implementation 'com.squareup.picasso:picasso:2.5.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test🏃1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

Below is the error message I'm getting

Hi @Eipeks. Apologies for the late reply. It seems that you have 2 Cloudinary dependencies (or other dependency conflicts) with different versions. Could you please run gradle dependencies and send us the output tree?
